Mandibular defects resulting from tumor resection or traumatic injuries can lead to considerable functional and aesthetic limitations on the patients. These defects disrupt a range of mandibular functions, primarily compromising mastication by impeding the mandible ability to form a stable opposition to the maxilla. Furthermore, it affects speech, swallowing, breathing, and alters lower facial contour which negatively changes facial aesthetics. Extended temporomandibular joint reconstruction (eTMJR) presents a helpful surgical modality in such complex presentations with significant bony involvement. This technique surpasses the limitations of conventional TMJ reconstruction by including the reconstruction of concomitant mandibular and/or temporal bone abnormalities. This case report is for a 42-year-old male who underwent extended total mandibular joint replacement surgery to address a significant left mandibular defect extending to the midline. Preoperative planning incorporated advanced techniques involving 3D printing, digital planning, and surgical guidance. The patient received a transitional removable partial denture to replace missing teeth and to achieve the planned occlusion intraoperatively. At the six-month follow-up, the patient demonstrated outstanding clinical outcomes.
